Removing equipment
1 Software disable the controller card (and all cards connected to the
controller):
LD 32
DSXP x
2 Turn off power to the column or the module power supply and ringing
generator (if equipped):
— With AC power, set the main circuit breaker for the column to OFF
(down) in the rear of the pedestal.
Due to hazardous voltage in AC-powered systems, power to the entire
column must be shut down. This shuts down all functions in the
column.
— With DC power, set the switch on the NT6D40 PE Power Supply
and NT6D42 Ringing Generator to OFF (down). Set the circuit
breaker for just this module to OFF (down) in the rear of the
pedestal. (All other modules in the column retain power.)
